Abstract

The invention provides a thin-type button switch which comprises a rubber cover, a base, a movable terminal and a static terminal. The rubber cover is provided with a rubber face which inwards extends to form a pressing portion, the upper surface of the base is downwards provided with a groove, two convex columns are arranged in the groove, the movable terminal is provided with a first contact portion which is positioned below the pressing portion, each of the left side and the right side of the first contact portion extends to form a first overlapping connection portion, the first overlapping connection portions are connected below the convex columns in an abutted manner, and the static terminal is provided with a second contact portion which is positioned between the convex columns and below the first contact portion. The pressing portion drives the first contact portion to move downwards by pressing the pressing portion, and the first contact portion is connected with the second contact portion in an abutted manner, electric conducting connection between the movable terminal and the static terminal is realized; due to thinning design, product thinning is realized; due to a pure mechanical contact mode, product reliability is improved, product service life is prolonged, and product cost is lowered.

Description

technical field [0001] The invention relates to a thin key switch. Background technique [0002] In view of the fact that there is no mechanical key switch on the current notebook computer or related similar products, and the requirement of the notebook computer or related similar products on the key switch itself is very thin, the inventor invented a kind of switch that can be applied to notebook computers or related similar products.
